Feel free to punch in holes and stuff. Everyone loves poking fun at the class that'll get its talents totally messed up in 1.10.
Hypothesis: Priests are a top nuking class in the game. With Smite.
In order to get his nuking potential, the priest has to spec deeply into Holy (31) and the obligatory Discipline (20). Check out the Talent Tree.
Combos:
- Focused Casting, Holy Nova

- Smite
- Whatever prissy healing stuff you do as usual.

Problems:
- Holy tree. It's gimped.
- Shadow tree. This build hasn't got any talents in that tree!
- Smite is 2.5s base casting time and benefits 71% from +dmg gear.
- Holy only at 150% damage on a critical.
- A holy priest who doesn't have Subtlety.
Benefits:
- You'll die just as fast, so talents don't really matter anyway.
